Published Unveiling Inaoside A: An antioxidant derived from mushrooms
(via sciencedaily.com) Original source Natural products have unique chemical structures and biological activities and can play a pivotal role in advancing pharmaceutical science. In a pioneering study, researchers discovered Inaoside A, an antioxidant derived from Laetiporus cremeiporus mushrooms. This breakthrough sheds light on the potential of mushrooms as a source of therapeutic bioactive compounds.
Published Study explores impacts of Arctic warming on daily weather patterns in the U.S.
(via sciencedaily.com) Original source Arctic sea ice is shrinking as the world continues to warm, and a new study may provide a better understanding of how the loss of this ice may impact daily weather in the middle latitudes, like the United States.
Published Anemonefish are better taxonomists than humans
(via sciencedaily.com) Original source Scientists reveal new lineages of giant sea anemones in Japan and their surprising associations with anemonefish.
Published Halloween toy among plastics swallowed by sea turtles
(via sciencedaily.com) Original source A Halloween toy was among hundreds of plastic items found in the guts of dead sea turtles in the Mediterranean, a new study reveals.
Published Research sheds light on new strategy to treat infertility
(via sciencedaily.com) Original source New research describes the science behind a promising technique to treat infertility by turning a skin cell into an egg that is capable of producing viable embryos. The technique could be used by women of advanced maternal age or for those who are unable to produce viable eggs due to previous treatment for cancer or other causes. It also raises the possibility of men in same-sex relationships having children who are genetically related to both parents.
Published New study discovers how altered protein folding drives multicellular evolution
(via sciencedaily.com) Original source Researchers have discovered a mechanism steering the evolution of multicellular life. They identified how altered protein folding drives multicellular evolution.
Published Mutation solves a century-old mystery in meiosis
(via sciencedaily.com) Original source A team deciphers complicated mechanism underlying genetic diversity.
Published Mapping the future's sweet spot for clean energy and biodiversity
(via sciencedaily.com) Original source A new study of Joshua trees, kit foxes and solar energy developments highlights the need to consider climate-induced range shifts for species as we expand clean energy.
Published Researchers develop artificial building blocks of life
(via sciencedaily.com) Original source For the first time, scientists have developed artificial nucleotides, the building blocks of DNA, with several additional properties in the laboratory.
Published A better handle on the emissions budget for the Paris climate targets
(via sciencedaily.com) Original source Scientists have found a new way to calculate the total carbon emissions consistent with the Paris climate targets of 1.5 degrees Celsius and 2 degrees Celsius of global warming.
Published Researchers open new leads in anti-HIV drug development, using a compound found in nature
(via sciencedaily.com) Original source A team of researchers has successfully modified a naturally occurring chemical compound in the lab, resulting in advanced lead compounds with anti-HIV activity.
Published Vitamin A may play a central role in stem cell biology and wound repair
(via sciencedaily.com) Original source Retinoic acid, the active state of Vitamin A, appears to regulate how stem cells enter and exit a transient state central to their role in wound repair.
Published New study reveals insight into which animals are most vulnerable to extinction due to climate change
(via sciencedaily.com) Original source In a new study, researchers have used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results could help to identify species most at risk today from human-driven climate change.
Published Rock weathering and climate: Low-relief mountain ranges are largest carbon sinks
(via sciencedaily.com) Original source For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such stable temperatures, Earth appears to have a 'thermostat' that regulates the concentration of atmospheric carbon dioxide over geological timescales, influencing global temperatures. The erosion and weathering of rocks are important parts of this 'thermostat.'
Published How does a virus hijack insect sperm to control disease vectors and pests?
(via sciencedaily.com) Original source A widespread bacteria called Wolbachia and a virus that it carries can cause sterility in male insects by hijacking their sperm, preventing them from fertilizing eggs of females that do not have the same combination of bacteria and virus. A new study has uncovered how this microbial combination manipulates sperm, which could lead to refined techniques to control populations of agricultural pests and insects that carry diseases like Zika and dengue to humans.
Published The Malaria parasite generates genetic diversity using an evolutionary 'copy-paste' tactic
(via sciencedaily.com) Original source All modern Plasmodium falciparum, the deadliest malaria parasite in humans, are descendants of one initial infection and so are very closely related, with relatively limited genetic differences. A long-standing mystery in the field has revolved around a very few locations in the P. falciparum genome where there are 'spikes' of mutations -- far more than anywhere else. Researchers have identified two genes in which these unusual mutation spikes result from DNA being copied and pasted from one gene to another.
Published Loss of nature costs more than previously estimated
(via sciencedaily.com) Original source Researchers propose that governments apply a new method for calculating the benefits that arise from conserving biodiversity and nature for future generations.
Published First atom-level structure of packaged viral genome reveals new properties, dynamics
(via sciencedaily.com) Original source A computational model of the more than 26 million atoms in a DNA-packed viral capsid expands our understanding of virus structure and DNA dynamics, insights that could provide new research avenues and drug targets researchers report.
Published Cracking epigenetic inheritance: Biologists discovered the secrets of how gene traits are passed on
(via sciencedaily.com) Original source A research team has recently made a significant breakthrough in understanding how the DNA copying machine helps pass on epigenetic information to maintain gene traits at each cell division. Understanding how this coupled mechanism could lead to new treatments for cancer and other epigenetic diseases by targeting specific changes in gene activity.
Published What makes a pathogen antibiotic-resistant?
(via sciencedaily.com) Original source In a comparative study, researchers describe how two notable pathogens -- Escherichia coli and Acinetobacter baumannii -- employ distinctly different tools to fend off antibiotic attack by two different drugs.
